Abstract

A motorized personal transportation article is described which transports a person by wearing a pair of power-assisted motorized shoes, wherein the shoes provide an increase in a user's walking speed in a forward walking action through supplementary motion of moving or propelling means based on an intended walking speed of the user, such that when a user's intended walking speed changes or when a user intends to substantially decelerate or immobilize, the speed of the supplementary motion can be adjusted before the step is completed. The sole of each of the shoes houses at least one plate coupled to moving or propelling means such as conveyor assemblies, and the moving or propelling means are designed to neutralize forces acting to disrupt the operation of the moving or propelling means during a forward walking action or the balance and comfort of the user.
